Description
Technical field
The invention belongs to fire-fighting fire extinguishing field more particularly to a kind of standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane.
Background technique
In existing gas extinguishing system, standby pressure type Fire-extinguishing System of Septenary-Fluorine Propane distinguishes heptafluoro-propane and high pressure nitrogen
In different holding bottles, after control system starting, high pressure nitrogen is first rapidly injected in the holding bottle equipped with heptafluoro-propane,
Heptafluoro-propane is pushed into fire-fighting network management and finally spurted in applicator as power gas and is put out a fire.But in existing system
In, it is possible to it will appear following defect:
(1) situation that heptafluoro-propane holding bottle does not enable after high pressure nitrogen holding bottle enables, with high pressure nitrogen
The injection of (15MPa), pressure in heptafluoro-propane holding bottle is considerably beyond the safe pressure (5.6MPa) in itself holding bottle
And explosion situation occurs, to cause safety accident；
(2) in combined distribution system, to meet all protection zone extinguishment requirements of distribution, extinguishing chemical must be reduced and filled
Dress rate increases steel cylinder quantity, management and troublesome maintenance；
(3) once starting, extinguishing chemical and high pressure nitrogen must all discharge system, cause the unnecessary wasting of resources, and
And the pressure in high pressure nitrogen holding bottle will gradually decrease in fire extinguishing procedure, initial high pressure nitrogen is rapidly injected can be to downstream
Connection equipment belt carrys out superpressure impact, and subsequent high pressure nitrogen gradually limits the conveying distance of extinguishing chemical；
(4) heptafluoro-propane holding bottle well known to can all have certain leakage, and long-term storage may cause fire-fighting dose not
It is able to satisfy extinguishment requirement, once fire occurs, if how storage process effectively stamps out a fire with the presence of leakage；
(5) even if extinguishing chemical pressure in transfer pipeline is sufficient, but since protection zone area is larger, a spray head is responsible for
Region more limit to, so that the spray head quantity of required installation is just more, cause the problem of cost and extinguishing effect difference.
